AUTOMOBILE-JACK Specification of Letters Patent.

Patented July 18, 1916.

' Application filed April 5, 1916. Serial No. 89,024.'

Another object is to produce a jack that is cheap to manufacture andefiicient in operation and that will allow for the automatic raising ofone end of the vehicle by simply running the vehicle over the apparatus.

lVith the foregoing and other objects in view the invention consists inthe combination and arrangement of parts to be hereinafter fullydescribed in the following specification and illustrated in theaccompanying drawings which form a part'of said specification and inwhich Figure 1 is a plan view of my improved automobile jack. Fig. 2 isa rear end view of the same. Fig. 3 is a side elevation showing amachine being moved into engagement with the jack. Fig. 4c is a similarview showing the machine engaged by the jack. Fig. 5 is a longitudinalsectional view taken on line 5-5 of Fig. 1. Fig. 6 is a fragmentarydetail view. Fig. 7 is a section taken on line 7-7 of Fig. 6. Fig. 8 isa fragmentary view showing the connection of one of the standards andthe frame of the jack. Fig. 9 is a section taken on line 99 of Fig. 8.

Like reference characters denote corre-- sponding parts throughout theseveral views.

The reference numeral 1 denotes a base block formed with transverselyextending grooves 3, 3 which serve as guides for the bolts 4 carried byangle pieces 5, 5 which are secured to the longitudinal brace beams 6, 6that run parallel with the sides 7, 7 of the jack frame and that areconnected thereto by the pivot bolts 8, 8 and by the bolts 9, 9, saidlatter bolts also connecting the oblique frame ends 10, 10 to the sides7 and beams 6 which latter members are spaced away from each otherthroughout their length as shown. At one end the said sides 7 and beams6 rest upon a lower sectional cross beam 11,12, each beam-section beingapertured'as at '13 and covered by a piece of metal plate 14 formed withan elongated slot 15 through which the connecting bolts 16 extend thatlock the beam-sections in adjusted relation. ,An upper sectional crossbeam 17, 18, of identically the same construction as the beam 11, 12 isprovided with the looking bolts 19 to secure its sections fixedlyinadjusted relation. A transverse brace beam of like sectional formationand designated by the numerals 20, 21 is provided with the locking bolts22 to permit itsadjustment as desired; said beams 17, 18 and 20, 21serving as stops for the standards 23 to be hereinafter described.

Upon the aforesaid pivot bolts 8 the standards 23 are arranged, saidstandards being formed with a plurality of bolt-receiving perforations2a to permit their adjustment with relation to the frame members 6, 7 toaccommodate automobiles having wheels of various diameters. It isreadily seen the jack frame can be adjusted in a horizontal plane bymeans of the cross beams that carry the beams 6, 6 and sides 7, 7; onebeam 6 together withone side 7 being jointly adjustable with relation tothe remaining beam and side 6 and 7; this adjustment having been abovedescribed. When the frame is set to accommodate an automobile the.machine is run over the jack until one of itstial character oftheinvention is not,

modified.

What is claimed is 1. In an automobile jack, a base block, a loweradjustable cross beam, a frame formed of relatively adjustableframe-sides connecting said base block and adjustable cross beam, andstandards pivotally arranged in said frame-sides.

2. In an automobile jack, a base block, a lower adjustable cross beam, aframe formed pieces and slidably disposed in the grooved portions ofsaid base block, standards pivotally arranged in said frame-sides, andmeans adj ustably connecting said frame-sides whereby the pivotalmovement of said standards is limited.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two subscribing Witnesses.
